Windows 11/10 OS is designed to expend less energy in an attempt to save more power. This is intended to be achieved by auto-turning off the display when no activity is reported. However, this is not always the case. At times, you might not be near the computer but don’t want it to shut off the display or go into standby after every few seconds. So, how do you prevent computers from Sleeping or Locking? Simple: by using Caffeine.
Prevent computer from Sleeping or Locking
Caffeine is a simple and lightweight utility that prevents your machine from slipping into standby mode, thereby stopping sleep mode from coming into effect. The program offers a simple solution for preventing your computer from going into standby mode or shutting down. It does this by deceiving Windows via a simulation method.
A cup of coffee ideally contains 80–175 mg of caffeine, depending on the quality of beans used, sufficient to temporarily make you feel more awake and energetic. However, all that caffeine application requires to temporarily keep your machine awake is a key press simulation once every 59 seconds. Moreover, it does not give your machine jitters like caffeine in a cup of coffee.
Once downloaded and installed, the application silently resides in the system tray and displays a control panel if you right-click the icon. This panel offers simple activation or deactivation options and time spacing (1 to 24 hours) to keep the computer alive. You can replace the function of the default F15 key with the Shift key.
Apart from these, the software features support for various command-line options, thereby giving you some additional ways to customize the application’s behavior. Additionally, you can set it to emulate the Shift key instead of the default F15 combination to prevent sleep but, at the same time, allow the screensaver to launch and start the software disabled.
